VENTlLATlNG GURNIOE OR EtTRlP.

SPECIFICATION forming part of Letters Patent No. 780,247, dated January 1'7, 1905.

Application filed August 20, 1901. Renewed December 8, 1904. Berial No. 236,049.

To all! whmn it warty concern.-

Be it known that I, TnoMAs H. VVILooX, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Ventilating Cornices or Strips, of which the following is a specilication.

My invention consists of a new article of manufacture comprising a strip or sheet of metal formed in cross-section as a single piece of metal and having openings in it, said strip or sheet being of such form as to adapt it to be applied to the surface of the ceiling or to the Wall of a room and to thereby form an airpassage, one wall or surface of which is the sheet-metal strip, while the other wall or surface is the wall or ceiling of the room.

My invention consists, further, in the new article of manufacture comprising a strip of metal adapted for use as a ventilating cornice or molding and having a picture-molding formed integrally with it.

One of the chief uses of my invention is for the ventilation of apartments and confined spaces which are provided with insuflicient means for the escape of foul air or gases accumulating in them.

My improved strip when applied at the location designated and when the inclosed space behind it is connected with a suitable escape line or ductis especially well adapted to carry oil noxious air or gases, being located where the heated or foul air and gases naturally accumulate.

Figure 1 is a general vertical section of a portion of a building equipped with my improved strip cornice or molding and showing the connection of the spaces inclosed by the strips with a proper escape-flue wherein a circulation of air is produced artificially for ventilating purposes. Fig. 2 is an enlarged cross-section of the improved strip,taken along the line a a, Fig. 1.

Referring to the drawings, the strip itself is indicated by the numeral 1. The strip in cross-section has bends or curves proper for giving the same somewhat the appearance of an ornamental molding, but has its edges turned at such angle as to enable them to fit against the wall and ceiling of a room to form an inclosed space in the corner or cove. These flat portions may be used for the attachment of the strip by means of brads or nails driven through them. The said strip is also provided with a bend or offset 10, formed upon the strip in the process of manufacture and adapted, as indicated, to constitute a picturemolding.

The strip is provided with any desired number of openings 3, which may be of any form or configuration and adapted to allow the air to llowinto or from the space behind the strip and, from thence through passages 5 in the wall or ceiling of the room to a proper flue or pipe, which in a system of ventilation would be by preference a vertical escape through a pipe 6.

The spaces inclosed by the strips in contiguous rooms or apartments would be connected by the passages 5, as indicated clearly in Fig. 1, if desired, or connection might be made direct from each room to a suitable fine 6.

1n constructing the strips it is preferable to regulate the size of the openings 3 to thedistance of the strip or of the apartment wherein it is used from the escape-flue 6.

In case my strip or molding is used for ventilating purposes the spaces may be connected with an escape-line 6, in which an artificial circulation is produced in order to assist the circulation of the heated gases from the apartments where the strip is applied. Thus, as indicated in Fig. 1, a suitable compressor 8 may supply air under pressure to escape-noz-- zles 9, located in the line (3 near the openings 5 and acting to induce acirculation by the injector principle. If desired, however, other means might be employed for this purposeas, for instance, an exhaust appliance at the top of the flue or suitable gas-burners located in the flue to heat the air therein and produce an upward circulation.

As will be readily understood, dampers may be placed at suitable points in the air-passages to regulate or control the flow of the air.

I claim as my invention- As a new article of manufacture, a strip or sheet of metal formed, in cross-section, as a single piece for attachment to the side walls and Ceiling of a room and perforated for the York and State of New York, this 19th day of pflxssa-ge of air from the room for ventilating} August, A. D. 1901. t e same, said strip or sheet having forme 7 along its face a head or projection for the re- THOMAS ILCOX' 5 eeption of picture-hooks substantially as set .Witnesses: forth. DELBERT H.
